Abstract: Faced with the lag challenge of traditional macroeconomic indicators in monitoring regional economic fluctuations, this study proposes a multi-modal public opinion knowledge graph construction method that integrates agenda setting and signalling theory. Through cross-modal coding, spatio-temporal fusion and graph structure learning, the massive heterogeneous graph-text public opinion data is transformed into a structured dynamic knowledge graph. Experiments based on the constructed Yangtze River Delta Regional Economy - Multi-modal Public Opinion dataset show that method achieves 78.3% accuracy in predicting the direction of regional quarterly gross domestic product growth rate, which is significantly better than a variety of frontier baseline models (p < 0.01), and performs well in the task of graph link prediction. This study constructs a theory-computational bridge connecting micro social perception and macro economy, and provides an interpretable new paradigm for intelligent research and judgement of regional economy.
Keywords: regional economic fluctuations; multi-modal public opinion; knowledge graph; signal theory; prediction accuracy.
